- Added a new version of auto_stretch. It seems to work better
bit it still needs improvement (a lot)
- Added TrueType support. This solves also a problem of missing
libraries if libgd needs -lttf or -lfreetype.

- Fixed path problems. Cvsroot and module will always have a
trailing '/' if they are not empty so that simple files
can be addressed directly from the commandline. This also
eases expansions.
- Implemented new features:
* revisions can have custom text
* background colors of boxes working
* boxes can have shadow (looks nice)
* imagemaps generate diff areas between revisions
- Several new config parameters to support above functionality.

Major update of the code.
- Complete new method of getting the revision structure by directly
reading the rcs/cvs file. This should also speed things a bit
because no external program needs to be called anymore.
This also means that "remote-graphs" are no longer a possible
extension of the program. But, who cares.
- Implemented branch-kerning to save place. The images are now
much smaller in width, dependent on the settings of the exterior
margins.
- Fixed disjoint braches by reading the structure direct from the
rcs/cvs file. The revision/branch structure is no longer determined
from the revision numbers, but solely from the rcs/cvs file structure.
- Fixed display of branches with no revisions attached to them. These
only have a tag describing the new branch.

This form allows you to request diffs between any two revisions of this file.
For each of the two "sides" of the diff,
select a symbolic revision name using the selection box, or choose
'Use Text Field' and enter a numeric revision.
